1 Claim.

This invention relates to improvements in air and gas washers, absorption towers, cooling towers and the like, and this application is a division of my co-pending application Serial No. 367,312 filed November 27, 1940, in which I show one embodiment of that invention in Figures 5 and 5a of drawing 2. I wish to make said embodiment the subject of this present application to more fully disclose the embodiment and to fully claim it separately and distinctly.

An object of this invention is to provide'an apparatus of more compact form and of a simpler construction than the other embodiments shown in my application Serial No. 367,312. Other specific objects of the invention will appear as the specification proceeds.

The invention is illustrated'in a, preferred embodiment by the accompanying drawing in which Figure 1 is a horizontal sectional view of the apparatus embodying my invention taken on, line l-l of Figure 2. Figure 2 is a vertical sectional view taken on line 2--2 of Figure 1. In the illustration given, the apparatus consists of a horizontal cylindrical casing divided into two chambers 2 and 2a by the vertical diaphragm 5 with hole in its center. Casing 2 which is provided with a tangential gas inlet 20 is designated as a preliminary washing chamber and easing 2a as a final washing chamber. Both chambers 2 and 2a communicate at the bottom throughslit S with a common sump chamber 3 which is provided with a drain or outlet 22.

Chamber 2a is provided on its interior with a disc baflle 8 concentric with and overlapping hole 0 of diaphragm 5. Between disc baflie 8 and diaphragm 5 are interposed circumferentially around hole 0 a series of impingement vanes 9. A liquid supply pipe 4 screwed into coupling 40 which extends through wall 2b is provided with a series of radial liquid distributing pipes 4a which supply liquid to interior wall of casing 2 and a series of radial liquid supply pipes 4b which supply liquid to impingement vanes 9.

The interior of casing 2a communicates with chamber 11 in which are disposed spaced spray eliminator plates l8 which are designed to separate any liquid particles from the cleaned gas. Chamber l'l communicates through connection IS with the inlet of exhaust fan I which exhausts the cleaned gas through outlet 2011.

Assuming that this apparatus is used for the purpose of cleaning dust laden air, the air enters casing 2 through tangential inlet 29. Because of such tangential entry. e ai is given a swirling motion and impacts the liquid issuing from the radially disposed pipes 4a and throws this liquid by centrifugal force against the interior wall of casing 2 carrying with it the heavier particles of wetted dust. This dust is washed down with the liquid through slot S into sump chamber 3 and oulet 22. The partially cleaned air continues to swirl through hole 0 of diaphragm 5 and through the impingement vanes 9 into chamber 2a. While swirling through vanes 9 the air carries with it the liquid that issues from the radially disposed pipes 427 and impacts the surfaces of impingement vanes 9 with great force and effectively impinging the fine particles of dust against the wetted surfaces of the vanes while the liquid washes the surfaces free from the impacted dust particles which are thrown by centrifugal force to the interior wall of chamber 2a from whence it drains to sump 3 through slot S.

The cleaned air passes between a series of eliminator plates l8 which efiectively remove any solid particles of liquid 'while the cleaned air free from solid liquid particles continues through chamber H to the inlet of fan I through connection I9 and then out through the fan discharge 20a.

Although the present invention has been described in connection with a specific embodiment thereof, it is not intended that such details be regarded as limitations upon the scope of the invention and in the accompanying claim, the words gas and air are used in their broad sense and include all gases and vapors.

I claim:

A washer for air and gas, comprising in combination a horizontally disposed casing, a ring diaphragm having a large central opening therein, in said casing, dividing it into a first chamber and a second chamber, tangential air inlet means in said first chamber, stationary means for spraying liquid radially outwardly into the gas swirling in said first chamber, a disk baiile larger than the opening in the ring diaphragm and fixed in said second chamber directly opposite to and spaced from the opening in the ring diaphragm, angularly placed, stationary swirling vanes positioned between the outer part of said disk baffle and the inner part of said ring diaphragm, and means for spraying liquid radially outwardly in all directions into and through said swirling vanes.
